One of the most important factors in maintaining an air conditioning unit is to keep it clean and well maintained. Good maintenance can not only reduce energy consumption and save monthly bills, but a clean condenser coil will also make your A/C unit have a longer service life and keep it running efficiently.

Under normal circumstances, it is recommended to clean the compressor coil and radiating fins of the outdoor unit once a year, but if there are a large number of plants or nearby cottonwood or dandelions, it should be cleaned once more. These are the culprits. For comfort and cost savings, this is the most routine chore you can perform on an air conditioning unit.

For this project, you will need a garden hose, a good spray foam cleaner and a fin comb if the fins are severely bent. Basic tools such as a wrench or screwdriver are required to remove the air conditioning unit cover. You also need to buy a store vacuum cleaner and a medium hardness brush (but be very careful when cleaning the heat sink, they are very fragile and easy to bend.

The machine has not been cleaned for at least two years. You will see a lot of dead grass clogging the fins.

If it is the first time, it may take an hour or more to clean the outdoor unit alone, so please give yourself enough time to do your work. If you do not complete the task, you can hire an HVAC professional to complete the task for you.
